Here is where you can order my book Physical
Mathematics for only $68 from Cambridge University
I plan to use Anthony Zee's book Quantum
Field Theory in a Nutshell, which is now in its second
edition. I will post pdf's of its first few chapters on this website
to allow students to read it before they get a paper copy. I
just now asked the UNM bookstore to order copies of this book
because one of you asked me to do so.

Here is chapter I.3.
Students may find the website
for the course in quantum field theory that I taught in 2010-2011 of
That web-page is arranged with the material of 523 at the top and
that of 524 below it.

systems of many variables.

relativity) is a discussion of classical electrodynamics in
the context of special relativity.
Here is that same section with some
added words about quantization.
Section 50 of chapter 11 is a discussion of Yang-Mills
